Doug there is no seperate motor for those headlight squirters. There is just an extra solenoid that leads to the headlights with hoses.
Those solenoids are not made in aftermarket and are VERY expensive on ebay if you can find one. Ive not heard of anyone rebuilding them either, if you can figure out how to fix one let us know. If the stubs are broken off, Im guessing there has to be a good epoxy to put a new stub on with, maybe cutting a stub off a new union or Tee you can get at any parts house for vacuum hoses. cut it off and glue on.
If your pump is not working for the windshield either then replacing the whole unit might be the way to go. Just remove the solenoids and replace on a new pump.
Im sure others will chime in here.
When you push the headlight switch to the right to run the windshield squirters, the lower solenoid is activated to open up and squirt thru the hoses it has on it.
If you HOLD that switch to the far right, the other solenoid (upper on top of wiper motor) is activated to open up fluid to the hoses attached to it, up to the headlights. The same pump works on both, the switch tells it which solenoid to activate. Hope that helps. Here is a diagram that Steve McCorry drew up to show you what goes where.
Just looked at my car and the #1 spot and the #2 spot hoses are in the wrong place. Hey, at least I had one out of three right!
Easy fix and as soon as I get my new carb dialed in I'll give it a shot.
Since there are two activation points in the RS windshield wiper switch for the squirter solenoids does that mean a wiper switch from a non-RS car wouldn't work?
Thanks much for the help, I appreciate it!!
Along with my wiper switch question can someone explain how the solenoid works. I pulled the round part off of my headlight squirter assembly. Remove one screw and it slides off of a plastic tube. No holes in the tube. How does the little solenoid change any water flows?
The drawing above is a little off. The two washer pump outlets (that normally go to individual windshield nozzles) get combined into on with the "Y fitting and get attached to nozzle #2. A single hose comes off of nozzle #3, Goes about 2" to a "Tee" fitting with a hose going from each end of the horizontal leg of the "Tee" to one of the two windsheild washer nozzles. The connection listed as being Nozzle #1 is the one that goes to the Headlight washers, in the same manner as the headlight washer, a single hose to a "tee" with two hoses going forward to the left and right washers, where another "tee" fitting splits the single hose to the two headlight sprayers.
